Aroma is an indispensable factor that substantially impacts the quality assessment of black tea. This study aims to uncover dynamic alterations in sweet and floral aroma tea (SFABT) throughout various manufacturing stages using a comprehensive analytical approach integrating gas chromatography electronic nose, chromatography–ion mobility spectrometry (GC-IMS), chromatography–mass (GC-MS). Notable volatile components were discerned during processing, predominantly rolling stage. A total 59...
In the present study, comprehensive quality of Congou black tea (CBT) including aroma, taste, and liquid color was investigated by a combination gas chromatography electronic nose (GC-E-Nose), tongue (E-tongue), eye (E-eye). An excellent discrimination different grades CBT accomplished through fusion GC-E-Nose, E-tongue, E-eye combined with orthogonal partial least squares discriminant analysis, parameters R2Y = 0.803 Q2 0.740. Moreover, quantitative evaluation successfully achieved...
Aroma plays a pivotal role in the quality of black tea. However, acceptability tea is greatly limited by green off-flavor (GOF) resulting from inappropriate processing control. In this study, key odorants causing GOF were investigated volatolomics, and their dynamic changes formation pathways in-depth understood. Significant alterations volatile metabolites observed withering stage. A total 14 identified as contributors to GOF, including 2-methylpropanal, 3-methylbutanal, 1-hexanol, nonanal,...
Abstract This study is aimed at the issue of energy waste resulting from significant fluctuations in consumption steam turbine system under flexible peaking demands coal-fired units. To accurately predict these units across a wide range load conditions, prediction model eXtreme Gradient Boosting (XGBoost) established. Firstly, variables are chosen based on existing measurements and an analysis power plant. Meanwhile, dataset its distribution calculated by Consumption Rate Analysis (CRA)....
The shaping process is recognized as a crucial step in the manufacturing of green tea. However, its influence on aroma quality remains unclear. In this study, effects four techniques, including flat tea (FGT), straight (SGT), phoenix (PGT), and curled (CGT), volatile metabolites were investigated by gas chromatography electronic nose (GC-E-Nose) chromatography-tandem mass spectrometry (GC-MS/MS). findings indicated that distinct processes significantly influenced development components PGT...
Spreading, the preliminary step in production of green tea, is crucial for achieving superior tea quality. This study investigated effects spreading on sensory quality and volatile compounds under varying intensities yellow light, employing GC-E-Nose targeted metabolomics. A notable improvement overall was noted samples subjected to a higher intensity 6000 Lux, which characterized by delightful floral fragrance. In total, 70 were successfully identified, with 61 volatiles detected across all...
Gardenia tea (GET) is one of the typical representatives Chinese scented and loved by consumers for its pleasant aroma. In study, volatile profiles GET were characterized gas chromatography electronic nose (GC-E-Nose), comprehensive two-dimensional chromatography-time-of-flight mass spectrometry (GC × GC-TOFMS) chromatography-olfactory-mass (GC-O-MS) combined with chemometrics. Satisfactory discrimination was obtained GC-E-Nose principal component analysis, cumulative contribution rate...
Geographical regions profoundly influence the flavor characteristics of Congou black tea (CBT). In this study, 35 CBT samples from 7 geographical were comprehensively characterized by integrated multiple intelligent sensory technologies and untargeted metabolomics analysis. A satisfactory discrimination was achieved through fusion (R2Y = 0.918, Q2 0.859). total 104 non-volatile 169 volatile metabolites identified UHPLC-HRMS GC-MS, respectively. Of these, 45 critical differential 76 pivotal...
Abstract Purpose The purpose of this study was to analyse the difference between arthroscopic fixation and open reduction internal (ORIF) posterior cruciate ligament (PCL) tibial avulsion fractures. Methods This retrospective analysed patients with an acute PCL fracture who underwent surgical treatment at our hospital follow-up for least 24 months. Variables based on sex, age, Meyers–McKeever type, method, meniscus tear, external fixation, labour or sports, Lysholm knee score, IKDC KT-1000...
Rolling plays an important role in shaping the characteristic quality of black tea. However, dynamic alterations volatile compounds during rolling process remain unclear, which hampers control In this study, changes Congou tea throughout were explored by a combination GC-E-Nose and GC–MS analysis. The results PCA PLS-DA revealed significant profiles, particularly at 15-min stage. A total 82 including eight categories identified process. most abundant volatiles aldehydes, alcohols, esters....
Laryngeal carcinoma is one of the most common tumors concerning otorhinolaryngology head and neck surgery, however, pathogenesis laryngeal remains unclear. MicroRNAs (miRNAs) have been reported to play vital roles in Herein, present study was designed explore function mechanism miRNA‑98 hypopharyngeal carcinoma. In brief, qRT‑PCR, MTT assay, western blot analysis, Transwell assay luciferase reporter were performed. Based on results, expression downregulated patients with Downregulation...
To investigate the efficacy of PD-1/PD-L1 inhibitors plus chemotherapy versus anti-PD-1/PD-L1 monotherapy in advanced microsatellite instability (MSI)/mismatch repair-deficient (dMMR) gastrointestinal cancers.We retrospectively recruited patients with MSI/dMMR cancer who received or without and compared objective response rate (ORR), disease control (DCR), progression-free survival (PFS), overall (OS) inhibitor (chemo-anti-PD-1/PD-L1 group) alone (anti-PD-1/PD-L1 group). Propensity...

Geographical regions profoundly impact the flavor characteristics of Congou black tea (CBT). In this study, 35 CBT samples sourced from 7 geographical were comprehensively characterized by integrating multiple intelligent sensory and untargeted metabolomics analysis. An excellent discrimination was achieved through fusion (R2Y = 0.918, Q2 0.859). A total 104 non-volatile 169 volatile metabolites identified UHPLC-HRMS GC-MS, respectively. Of these, 45 key differential 76 pinpointed based on...
Abstract The molecular categorization of colon cancer patients remains elusive. Gene set enrichment analysis (GSEA), which investigates the dysregulated genes among tumor and normal samples, has revealed pivotal role epithelial-to-mesenchymal transition (EMT) in pathogenesis. In this study, we employed multi-clustering method for grouping data, resulting identification two clusters characterized by varying prognostic outcomes. These subgroups not only displayed disparities overall survival...
Objective The surgical treatment of patients with ankylosing spondylitis and severe thoracolumbar kyphosis combined hip flexion contracture is very difficult for all the surgeons. femoral neck osteotomy (FNO) first step to break ice. evaluation a new modified FNO method important improve curative effect. Methods Five male nine bone‐fused hips who underwent were included from October 2021 March 2022. was designed that saw blade manipulated lateral base inferior part head, keeping Pauwels'...
